Dear Mr. Rothwell,
I was very impressed reading your exceptional well written essay, and I do hope that it does well in the competition. May I just point out a problem that you did not mention?
The only way your wonderful Nuclear Fission Reactors can be built is by using present day technological methodology. According to the Rachel Maddow television show broadcast in my area at 9:PM on March 12, 2014, the State of North Dakota is having to deal with trying to dispose of a daily production of about 25 tons of natural radio-active material embedded in the mesh sleeves discarded by the fracking and oil well companies. All technology is destructive of natural resources. An overwhelming amount of radio-active material would come into existence long before one of your fission power stations could be brought on line.
